Vista - Error 1054 (Userenv) since Migration to hyperv

Hi,
I was migrating a SBS 2003 to a HyperV-Host (Win2k8, RTM). The guest was
getting drive-imaged, hyper-v tools installed on the Win2k8 RTM-Version.
I am using the "Microsoft Virtual Machine bus Network" NIC & drivers in the
SBS 2003 guest. I am getting an error 1054 recorded by Userenv in the
Eventlog "Windows cannot obtain the domain controller name for your computer
network. (An unexpected network error occurred). Group Policy processing
aborted."

The underlying host-system is dual quadcore Intel. The SBS 2003 guest has 3
GB RAM and 4 CPUs assigned.

Network-Connectivity seems to be ok.

I've seen similar posts: http://forums.techarena.in/showthread.php?t=391655
which seemed to by AMD specific and a German post
http://www.microsoft.com/communities...&cr=&sloc=&p=1
which seemed to be a problem of upgrading the virtual integration tools from
RC to RTM.

Is anybody having the same issues? Any ideas how to solve?

Thanks
Charlie

Uuuups,

just re-read the supported GuestOS page on MS website:
http://www.microsoft.com/windowsserv...-guest-os.aspx
Windows Server 2003 x86 (VMs configured with 1- or 2 virtual processors SMP
only)
Windows Server 2003 Standard x86 Edition with Service Pack 2

Maybe the problem was to assign 4 virtual cpus - instead of the supported
2??

I will reboot tonight....
Charlie

Hm - I have reduced the number of vCPUs to 2. I am still getting the Userenv
1054 error every 5 minutes.

Any idea?

I had exactly the same issue... changing Hyper-V to 1 processor fixed it...

I had some problems when I first installed a Windows 2003 server VM, until I installed Legacy Network cards. Once they were installed all was ok. You'll need to shut down the guest, then go to settings, add the legacy cards, then restart the VM.

I've written a few articles on my experiences with HyperV on thecodefish.com website which can be read here: The Code Fish - Virtualization / .Net Development, SQL, Virtualization & Server Tutorials Hopefully they'll help a few people.
